Spoke Specificatio (mark or Dragonfly)
« on: 20 Jul 2023 at 13:13 »
As posted previously (now in the Wanted section) I have one broken spoke on my Dragonfly rear wheel (an inner I think); can anyone tell me with certainty the exact spoke specification in order to look for a new replacement? I would prefer to replace with a good original spoke, which someone must have lying around somewhere, but if I don't receive any replies I will look for a new one. NB I know all about CWC etc but FYI the have replied to my enquiry that they will only do a minimum of 10 and they want me to send them a sample! regards Chris

Hi Chris,

You might be able to find the original spec for the spoke, but your wheel may not be fully original. If the rim or spoke pattern has changed some time over the years and original spoke may not fit. This is why CWC want a pattern.

Presumably the broken spoke is still in the wheel. Best to extract the remains and get a replacement to suit. You need to specify the overall length (if a J-bend, measure from the inside of the bend to the end), the diameter (it might be butted - thicker at the hub end, or double butted - thicker at both ends), the bend angle (usually 85 degrees for an inner, but most replacement spokes are 90 degrees and will conform), and finally the nipple diameter (available in 0.025" increments).

I probably have something that I could modify to your spec. It takes about 5 minutes to cut and thread a spoke. However postage from Australia is now unreliable and ridiculously expensive. Welcome to the modern world. (Just got a petrol tap in a jiffy bag - 75 grams total - from the UK for the modest postage of 15 pounds.)

A month or 2 back, I received a small spanner in a jiffy bag from the UK.
For 2 pounds 20 pence postage.

Unlike ALL the other sellers, he went to the Royal Mail post office, and asked for economy international,
They still seem to have this service. It came by air, only took a day or 2 longer than all these instant delivery EXPENSIVE options
No tracking though.

I too have quite a range of NOS zinc plated spokes, in a range of lengths.
Plain unbutted. Will fit many a prewar wheel, if the specs are known.

Aye, riding around on a broken spoke is a disaster waiting to happen. !
If ye loose bit meets the tube ...
P.S. Breaking spokes is generally a sign the spokes are inadequate ??
